Kang-min Liu, a.k.a. gugod, came to Japan. After we took a lunch at Ginza district, he taught me about his current project Ebisu.js which a library implementing "custom events" handler in JavaScript.
We both Asian people talked in English. However, it's probably true that we could make communication smoother after we start to write JavaScript language. :-)
All JavaScript engineers in the world, let me know when you come to travel to Tokyo. We will welcome you. Let's talk thoroughly about JavaScript.
